this just started today. it sounds like a high pitched whistle or squeak when i get into the throttle and get off. Doesn't happen every freaking time but i've done it enough today to know it's real. The worst part is if it doesn't make this noise during throttle it will make the same sound only way softer when i apply the brakes. The brakes will do it a couple of times but it goes away quickly and does not at this point seem to effect braking in any way. So what the hell is this? got 74k and my last peformance mod was my zzp dp @ 67k and every damn service has been done on time to date. What gives?
